Key to Label Information
Products bearing the AP seal of ACMI are certified in a program of toxicological evaluation to contain no materials in sufficient quantities to be toxic or injurious to humans or cause chronic health problems.
Lightfastness
American Society for Testing and Materials (ASTM) ratings, conforming to standard D4236, have been used wherever possible. ASTM I and II are both regarded as permanent for artists’ use. Where ASTM have not tested a pigment, the internationally recognised Blue Wool Scale (BWS) ratings are used. BWS 7 & 8 are regarded as extremely permanent, BWS 6 is regarded as permanent.
Permanence
This indicates colours that have been tested for lightfastness in graded washes from full strength to pale dilutions, taking into account the quality of the binder and any chemical interaction between pigments and their environment.
